Not able to use hiredis with redis-py for server-assisted client-side caching

[mahudees]

Version: redis-py - 5.1.0b7, hiredis - 3.0.0

Platform: Python 3.9 in MacBook Apple M3 Pro

Description:
Trying server-assisted client-side caching with redis-py version 5.1.0b7, it worked fine without hredis. Tried with hiredis for additional performance, getting the following error once hiredis is installed and ran the script.
Does it require any additional change, from this https://redis.io/docs/latest/develop/connect/clients/python/redis-py/ came to know no additional changes is required for most of the cases.

#3324 hasn't release yet.

[mahudees]

Thanks for the reply, when can we expect it to be released.

No one knows. For the time being, use hiredis<3.0.

[mahudees]

Ok sure, Thank you.

#3324 was released but its still failing

hiredis                       3.1.0
redis                         5.2.1

Any update on this?

[jnrbsn]

Is there a workaround for this? It still doesn't work.

$ pip list | grep redis
hiredis 3.1.0
redis   5.2.1

>>> import redis
>>> from redis.cache import CacheConfig
>>> r = redis.Redis(host='localhost', port=6379, protocol=3, cache_config=CacheConfig())
>>> r.set(b'foo', b'bar')
